Application filed. May 23, 1913. Serial No. 769,520.

To all whom t may concern Be it known that I, HENRY H.IM0RETON, a citizen of the United States, residingv at Stony Point, in the county of Rockland and State of New York, have invented new and useful improvements in Gras-Burners, of which the following is a specification.

This invention relates to an improved gas burner, being particularly designed for use in the burning of Bunsen gases, z'. e., those gases in which the combustible ingredients are intermixed with the necessary volume of atmospheric air or oxygen to support the combustion thereof.

The invention has for its object the provision of improved means by which the illuminating eiiciency of a burner of this type may be materially increased.

A further object is to provide a burner of this character which may be readily placed in position or removed as desired and which is composed of so few parts that it cannot become deranged or get out or order.

A further object is to provide improved means whereby the burner may be regulated.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawings:-Figure 1 is a longitudinal sectional view illustrating my improved burner. Fig. 2 is a top plan view of the regulating cap. Fig. 3 is an enlarged transverse sectional view thereof.

Referring to the drawings, 10 designates a gas pipe leading from any suitable gas supply into the burner tube 11, the latter being provided with the usual gauze 12 ordinarily employed where an incandescent mantle, as 13, is utilized for illumination. The burner tube is provided with a flat plate or tray 14 provided with upstandng arms 15, serving as a support for a chimney 16. It will be noted that when the chimney is in place no air can enter the same from the bottom.

l have found, in dealing with Bunsen I gases, that if the outlet for the products of combustion in the chimney 16, is restricted the illuminating power of the gas is greatly increased, and the character of the illumination will vary as the size of the outlet of said chimney is varied. l accordingly provide a regulator comprising a cap 20 having an annular iange 2l adapted to fit over the upper end of the chimney 16, said cap being provided with openings 22 adapted to register with openings 23 in a rotating slide 24C secured to said cap. lf desired the openings may be covered with gauze. By rotating thel slide 24 the outlet from the chimney 16 1s increased or diminished, as may be, and the illumination correspondingly varied. For instance I have found that by igniting the gas as it is discharged from the burner tube, and with the upper end of the chimney open, and then placing my regulator attachment over the upper end of said chimney, the illuminating power of the gas is increased approximately twenty-ive per cent.

In practice the regulator 20 is removed from the chimney in order toignite the gas issuing from the burner. And after igniting said gas, the cap is immediately replaced. rlhe slide 2li is then adjusted to secure the desired illumination. Should the quantity of oxygen carried by the gas become diminished for any reason, the cap may be removed to permit atmospheric air to reach the burner.

Having thus explained the nature of my invention, and described an operative manner of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of the modes of its use, what l claim is 1. A gas burner of the character described comprising a burner tube provided with an imperforate chimney-'supporting plate, a chimney resting upon said plate and inclosing said burner tube, and a cap provided with a flat under surface resting upon and in close Contact with the upper edge of said chimney, said cap being provided with means for regulating the outlet of the products of combustion.

2. A gas burner of the character described comprising a burner tube, a chimney surrounding said tube closed at its bottom, and a cap provided with a flat under surface resting upon and in close Contact with the upper edge of said chimney, said cap being provided with means for regulating the outlet of the products of combustion.

3. A gas burner of the character described comprising a burner tube, a chimney surrounding said tube closed at its bottom, and a cap provided with a flat under surface resting upon and in close contact with the upper edge of said chimney, said cap being Copies ot this patent may be obtained for ve cents each, by addressing the vided with the outlet openings, and a rotatable slide controlling said openings.

In testimony whereof I have hereunto set my hand in 'presence of tWo subscribing Witnesses.
